$log_8 (32) = log_8 (8^{ \frac{5}{3}}) = \frac{5}{3} *log_8 ~(8)=\frac{5}{3}$

hope that helps

I need help bruv. For the function y=x^2 - 5x - 6 .

lara [203]

Answer:

a. Vertex = (2.5,-12.25)

b. y-intercept = (0,-6)

c. x-intercept = (6,0) ; (-1,0)

Step-by-step explanation:

Your equation is written as:

$y = ax^{2} + bx +c$

The easiest way to find the vertex is writing the equation this way:

$y = a(x-h)^{2}+k$

Being the vertex (h,k)

So first complete the square

$y = x^{2} -5x -6 \\y = x^{2} - 2(2.5x) -6 \\y = x^{2} - 2(2.5x) +2.5^{2} - 2.5^{2} -6 \\y = (x^{2} -2(2.5x) + 2.5^{2}) -6.25 - 6 \\y = (x-2.5)^{2} -12.25$

Vertex : (2.5,-12.25)

To find the y-intercept you need to replace the equation when x = 0 and get y

$y = (0)^{2} - 5(0) -6\\y = - 6$

To find the x-intercept you need to replace the equation when y = 0 and get x

$0 = x^{2} - 5x -6 \\0 = (x-6)(x+1)\\x = 6\\x = -1$

rodney bought a 25pound bag of dog food his dog eat 10and2/5poundsof foodinthe firstmounthand104/5poundsof the foodin the second

MakcuM [25]

Answer:

3⅘ lb

Step-by-step explanation:

(a) Amount eaten

Eaten = 10⅖ + 10⅘

Think of pounds as pies. Each pie has 5 slices.

10⅖ pies = 10 pies + 2 slices = 50 slices + 2 slices = 52 slices

10⅘ pies = 10 pies + 2 slices = 50 slices + 4 slices = 54 slices

Eaten = 52 slices + 54 slices = 106 slices

(b) Amount remaining

Remaining = Original – Eaten

Original = 25 pies = 125 slices

Eaten = 106 slices

Remaining = 125 slices -106 slices

Remaining = 19 slices Convert slices to pies

Remaining = 15 slices + 4 slices

Remaining = 3 pies + 4 slices Convert to mixed fraction

Remaining = 3⅘ pies Convert pies to pounds

Remaining dog food = 3⅘ lb

The probability that you roll a 5 on a six-sided die is start fraction one over six end fraction . The probability that you flip

Anarel [89]

I am not sure about the probability but I cant tell you these events are independent because u don't need to roll a five for a coin to land on heads
